Figure 1: Ultrasonography, OCT, and Angiography in case 1. A By a longitudinal B-scan on the 7 o’clock meridian, a dome shaped lesion of 1.4mm × 3mm on the posterior equator eye wall with high reflective smooth surface and low internal reflectivity was found. B The lesion diminished seconds after probe pressure. C Spectral domain OCT showed an elevated area in the inferiotemperal fundus. The neuralretinal layer and the retinal pigmental epithelial layer bulged into the vitreous with a 4067µm wide 790µm height dome shape, with normal reflectivity and good continuity. The reflectivity under the RPE layer was lowered. D During venous phase, FFA showed no abnormal lesions. E Corresponding ICGA showed enlarged vortex vein ampulla filled obviously with density vascular bundle. F The filling gradually diminished untill the late phase. No fluorescein leakage was found.
